I think that it depends on how much you carry.
In Chanel, I love my boy bags because I can wear them crossbody or doubled up. (I have 3: black, caramel, & off white). I don’t mind that the boys are out of fashion now, but you might. (I bought them after the trend but new from the boutiques. But you could probably find good deals in the resale market. I know a lot of utubers got rid of the caramel boy bag). The length of the flap on the boy bag is a bit annoying at first, learning curve, but it’s my favorite Chanel style (although no one else agrees, lol)
Chanel classic minis & wocs are always good. I actually like the reissue mini a lot & if I can find one that’s not distressed too much, I will buy.
One other tip I would say is that I love crossbody bags that can also be worn top handle. Since I wear so much color, I like the option of hand held if my clothing is darker. So, maybe check out wocs and minis with top handle? (I don’t always stick to Chanel. I have a lot of Dior, too, for this reason. My Chanel boy bags & Diors are my daily bags- some diors are 8+ years & still look amazing for this reason). Chanel trendy cc sometimes has lovely options.
I love the 31. It’s darling. I hope that you really get good use out of yours.
Again for overall recommendations, I think it depends on how much you need to carry, how much weight you can tolerate on your shoulder as well as your budget.
Good luck, dear!
